Abstract

We experimentally demonstrate a silicon-on-insulator microring resonator filter that uses bent contradirectional couplers to eliminate the filter's free spectral range. The filter's measured side-mode suppression is greater than 15 dB, the extinction ratio is ∼19 dB, and the 3-dB bandwidth is ∼23 GHz.

Abstract

We propose a Vernier assisted Mach-Zehnder modulator (VAMZM) design that employs phase modulation on series-coupled Vernier rings' suppressed notches at the through ports to achieve a large extinction ratio and a small insertion loss.

3. An FSR-free silicon resonator reflector using a contra-directional coupler and a Bragg reflector

Abstract

We demonstrate theoretically a silicon resonator reflector, having no free spectral range, using a distributed Bragg reflector and a contra-directional grating coupler. The spectral response of the device meets numerous commercial specifications for a clear window of 5 GHz and a channel spacing of 100 GHz.
